FILTER-FUNNEL.

SPECIFICATION forming part of Letters Patent No. 588,369, dated April30, 1895.

Application filed February 16, 1895. Serial No. 538,699. (No model.) Y

To all whom it may concern.-

Be it known that I, ARcIDAs FARMER, a citizen of the United States,residing at Ohicago, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in Filter-Funnels; and I dodeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same, reference being had to theaccompanying drawings, and to the letters of reference marked thereon,which form a part of this specification.

My invention relates to that class of funparticularly for drawing liquorfrom a cask and placing it in a decanter and has for its object theprovision of means for properlyfiltering the liquor as it passes throughthe funnel.

The invention consists of a filter or sponge, charcoal, and screens ofgauze or perforated metal introduced into the tube ofthe funnel.

It consists further of special means for manipulating the valve.

In the drawings, Figure l is a vertical cen tral section of the funnel.Fig. 2 is a plan section ou the line 2 2 of Fig. l. Fig. 3 is a detailof the valve controlling mechanism. Fig. 4 is a plan section on the line4. fl of Fig. l; and Fig. 5 is an elevation of one ofv the screens usedin the funnel tube.

The bowl, A, of the funnel is preferably of spun copper and terminatesat the bottom in a short downwardly projecting neck, o., which isslightly tapering. l

The tube B, of the funnel is tapering in form and its lower portion islongitudinally fluted as indicated at b, in the manner common in funnelsfor the purpose of allowing suitable air vents at its sides. The upperend of the tube is of greater/diameter than the neck, d, and ispermanently secured to the bottom of the bowl A, preferably by the useof solder. VA plug valve, O, is adapted to lit within the neck, a, whichserves as its seat. By the use of this tapering form of valve and seatit is not necessary to have any additional guide to secure the trueseating of the valve, and consequently I secure a much larger and freerpassage from the bowl to the forated or reticulated material conical inl form is located within the lower end of the tube B, its base beingsecurely attached to the inner surface of the tube, at or adjacent toits mouth. By using the conical form of screen a much greater area issecured than would be attained if the strainer were flat. The spacebetween the two screens D, and F, is filled with a filtering material G,such as charcoal, and the space above the screen D, is fllled with asponge, E, which may be con- Veniently inserted and removed through thevneck a.

The valve, C, is controlled by a thumb latch, I-I, pivotally attached tothe top of the handle K, of the bowl A, and connected to the valve bymeans of a bent rod h, whose lower end fits loosely within an aperturedboss, c, on the top of the valve O. A spiral spring M, is interposedbetween the outer end of the thumb latch H, and the top of the handle K,so as to throw up the latch and thereby hold the valve O, normally toits seat. A catch is provided for holding the outer end of the latch H,down, and the valve C, open and consists 0f the two members o, p,attached respectively to the under side of the latch H, and the uppersurface of the handle K, and being adapted to auto1nati cally engageeach other when the latch is depressed. These catches are preferablylocated Within the spring M, and have their ends beveled for slidingcontact. The spring M, holds the two catches firmly in alignment andthey are disengaged by lateral pressure upon the latch H.

I am aware that 1t is not new to use a fun-'j IOO practice isobjectionable because the felt is apt to be dirty and the method ofholding the valve open is very awkward.

I claim as my invention- 1. The combination in a funnel, having a bowlA, and tube B, of a valve for closing the passage from the bowl to thetubo, a transverse screen D, within the tube, a screen F, at the lowerend of the tube, filter- Io ing material between the two screens and asponge between the screen D, and the valve, all substantially asdescribed.

2. The combination in a funnel of the bowl, A, the tube B, the valve C,for closing the 15 passage between the bowl and the tube, a

spring latch for controlling the valve, loclcing catches for holding thevalve open, a transverse screen D, within the tube, a conical screen F,set in the mouth of the tube, filtering material as charcoal interposedbetween the screens D, and F, and a sponge E, above the screen D,substantially as dcscribed and for the purpose set forth.

In testimony whereof I affix my signature in presence of two witnesses.
